Asterisk sign on corona documentation means ..?

We can see several asterisk(*) sign on http://docs.coronalabs.com/api/index.html

Some are followed by (*), like ads.*, analytics.*, but some are not.

Sorry for being silly, but i don’t see any note about it.

Soo what does the *asterisk* mean …?

For example:
You have physics library. This library has methods like physics.addBody(), physics.start() and so on.
physics.* just means that we talks about physics library which functions characterize with physics dot and some function name (start, addBody) calls. Asterisk is meaning this ‘some function’.
